Many people are wondering why did Christina leave Grey's Anatomy after 10 seasons. Frankly, it was time for her to go. Her plot line was getting old and it seems like every season she was even more of an emotional mess than she was before. For me, this got to be a huge turnoff of the show and one of the main reasons that I quit watching it all together. In my opinion, no matter what the reason was, Oh leaving the show was the best thing that ever happened. The show was essentially over after season 5 anyway when most of the really good actors starting taking on other roles. Christina was definitely one of those characters that clung to a dwindling story line for dear life and no matter how hard I tried, I couldn’t like her and was glad to see her go! She was bringing nothing but boredom to my TV screen every week the show was on.
